To be honest Aimc I wouldn’t bother for a Herb garden as most herbs come from semi desert conditions with very poor soil and pretty hot conditions, but if you wanted to I would use a soaker hose (a hose pipe with tiny holes in it with a bung at the end attached to an outside tap or water butt with a timer valve on it). On the other hand for a green house that’s much more worth automating
I’m still gathering the parts for my GH project Tho’ I still don’t know whether to go solar or mains (tho’ mains is tricky for me living in rented accomadation and solar is tricky in the UK)
I finished mine yesterday and it is very basic so far. I put a spare 180L water butt into my green house. I had a spare 2000/lph pump from my old marine tank. Got a cheap drip irrigation kit inc Adjustable Drippers. Got power from the garage to the greenhouse, the plugged it all into a basic on/off zwave socket. Got it timed via HA to come on at 6am for 2 minutes each day… It waters my 12 tomato plants, 2 basil, 6 chilli, 1 cucumber and 1 aubergine plants. I have a couple of extra Audrino boards coming to see how I can incorporate one to check for water level, soil dryness etc.
I did the same thing, however it seems that ive created a siphon in the process. When I switch it on, it works well. But when I switch it off, it still works! Although the water flow is slow, it will be enough to empty my 200L water butt over a period of hours, and drown my plants
I tried a pin hole at the top of the hose just above the water butt itself. While that stopped it siphoning, I think i made it a bit too big and lost any sort of pressure that is needed to get water down to the drippers. Now I need to replace that hose!
Did you encounter this?
If so, how did you eliminate it without losing the ability to water?
Im guessing i need some kind of inline valve, so i’ll do a bit of research too
